Things are always changing. Part of being successful here is being comfortable with not knowing what's going to happen.

My most radical shift was leaving Intel and joining Google, a small startup at the time, even though I was pregnant.

The reason I like my job is that I have this desire to create. I have this desire to create things and build things, and Google has enabled me to build and create things and to build products that are used by people all over the globe.

From phones to cars to medicine, technology touches every part of our lives. If you can create technology, you can change the world.

There are unlimited opportunities for display advertising. In fact, we're in the process of massive change in the display industry - how it's bought, how it's sold, and how it's targeted.

Let's face it: Engineering companies in general have more men than women. Google has tried really hard to recruit women. On the other hand, we have a standard. Google tries to recruit the best engineers.

We are a consumer company and our success is directly linked to our users trusting us. Therefore we have the same incentive as the user: they want to see relevant advertising so their experience of Google is positive and we want to deliver it.
